I never said i wouldnt use one.... i looked into it...... i just said i wouldnt split gears with it in drag racing....

Unless the prices have come down, I believe that I paid right around 2300 for the unit. I already had a Denny's Nitrous Ready DS, so I sent it back and had it shortened to work with the combination. Here is a link to the pricing off the GV website...http://www.gearvendors.com/prices.html. Doesn't look like prices have dropped, unless pricing is cheaper through a distributer.
I'd be interested to hear your results with the unit and the glide, most of the results that I have seen are guys with TH400s.

Pulled this off their website:
"Splitting the ratios (especially 2nd-over) is always valuable to the 3-speed car. 1st-over can be very valuable for hooking up with our AutoLaunch circuit on cars up to about 800hp but is a big torque multiplier and so cars with higher hp may break traction depending on their chassis setup. 2nd-over keeps the converter tight and produces torque multiplication right when the aerodynamics are starting to load the car heavily. We've never heard of a car that didn't run quicker going 1st, 2nd, 2nd-over then 3rd. A 1.28 deeper rear gear (the reciprocal of our ratio) can be used and the run 3rd-over for 5 to 6-speeds. With a 1.28 lower differential these cars can then also keep stock 1-2 ratio (instead of aftermarket deep gear) in the trans for less r.p.m. drop on shift.
Consistency and E.T. are improved by operating the engine and converter in a tighter rpm range as well as having more torque multipliers through the run. The GEAR VENDORS is one of the few products that can improve both. Study the Final Drive Ratio charts in the 2-wheel drive section appropriate for your tranny make and also read the powerglide section.
Hoserpower = Torque X RPM/5252 The Gear Vendors Under/Overdrive is one of the few products you can use to boost both sides of this equation. Keeping both the torque multiplication higher (gears are multipliers of torque) and the rpm tighter with the close ratios provide by gear-splitting. Your torque converter is also a torque multiplier. One of the benefits of gear-splitting is that all converters work better with the shortest steps in gearing. With close ratios there is also less need for high stall but we will keep any converter hooked up stronger."
Just trying to undestand why you wouldn't use it to split gears at the track? Seems like they have some real world results of several cars with improved before and after ET's. Appreciate the discussion!

no its not 100% accurate. just what we have seen on the dyno. remember for those that forgot or dont know, the GVOD is nothing but a small transmission that sits inline behind your TH400. so its another transmission (small) to suck up power through heat and resistence.

That is true...... but for those of us with power at a twist of a **** can over come that LOL

I think it would be worth it to me if i ever did go with it.... th epower it would eat up, it would make up for it having OD on the freeway..... even though its not bad now..... 2500=56mph....... speed limit is 55mph here......
